70 | /* This file controls the IO interactions between gdb and curses. |
71 | When the TUI is enabled, gdb has two modes a curses and a standard | |
72 | mode. | |
73 | ||
1cc6d956 MS |
74 | In curses mode, the gdb outputs are made in a curses command |
75 | window. For this, the gdb_stdout and gdb_stderr are redirected to | |
76 | the specific ui_file implemented by TUI. The output is handled by | |
77 | tui_puts(). The input is also controlled by curses with | |
78 | tui_getc(). The readline library uses this function to get its | |
79 | input. Several readline hooks are installed to redirect readline | |
80 | output to the TUI (see also the note below). | |
a198b876 SC |
81 | |
82 | In normal mode, the gdb outputs are restored to their origin, that | |
83 | is as if TUI is not used. Readline also uses its original getc() | |
84 | function with stdin. | |
85 | ||
1cc6d956 MS |
86 | Note SCz/2001-07-21: the current readline is not clean in its |
87 | management of the output. Even if we install a redisplay handler, | |
88 | it sometimes writes on a stdout file. It is important to redirect | |
89 | every output produced by readline, otherwise the curses window will | |
90 | be garbled. This is implemented with a pipe that TUI reads and | |
91 | readline writes to. A gdb input handler is created so that reading | |
92 | the pipe is handled automatically. This will probably not work on | |
30baf67b | 93 | non-Unix platforms. The best fix is to make readline clean enough |
1cc6d956 MS |
94 | so that is never write on stdout. |
95 | ||
96 | Note SCz/2002-09-01: we now use more readline hooks and it seems | |
97 | that with them we don't need the pipe anymore (verified by creating | |
98 | the pipe and closing its end so that write causes a SIGPIPE). The | |
99 | old pipe code is still there and can be conditionally removed by | |
